“The first head-to-head comparison of docetaxel and abiraterone acetate for high-risk prostate cancer patients starting long-term hormone therapy found benefit with both treatments when added to androgen deprivation therapy (ADT). Treatment decisions may come down to specific toxicities, which differ between the treatments.
“The large STAMPEDE trial previously found that both docetaxel and abiraterone improved outcomes when compared with placebo. “Right now, oncologists and urologists want to know which combination is preferable, which is why we conducted this analysis,” said study author Matthew Sydes, MSc, a statistician at University College London.”
“In patients with metastatic triple negative breast cancer (TNBC), turning a nonimmunogenic (“cold”) tumor into an immunogenic (“hot”) tumor appears to be feasible, thereby improving sensitivity to immune therapy with nivolumab (Opdivo).
“In a phase II study of 50 patients with metastatic TNBC who received palliative chemotherapy, priming the immune system with low-dose chemotherapy for 2 weeks or radiation therapy before starting nivolumab resulted in a best objective response rate (ORR) of 24%, announced Marleen Kok, MD, at the 2017 ESMO Congress in Madrid.”
“Eli Lilly and Co.’s experimental breast cancer drug abemaciclib significantly cut the risk of disease progression in a late-stage trial, bolstering the drug’s potential to become a new source of growth for the Indianapolis pharma’s oncology business.
“Updated results from a late-stage study known as MONARCH 3, presented over the weekend at the European Society of Medical Oncology’s annual meeting, showed abemaciclib in combination with an aromatase inhibitor extended progression-free survival in previously untreated patients with metastatic breast cancer.
“Eli Lilly has previously said abemaciclib could be best in class, yet it’s not clear whether the data disclosed to date will be enough to outshine rival drugs already marketed by Pfizer Inc. and Novartis AG.”
“Osimertinib improves progression-free survival by 54% compared to standard first line therapy in patients with EGFR mutated non-small-cell lung cancer (NSCLC), according to late-breaking results from the FLAURA trial presented today at the ESMO 2017 Congress in Madrid.
“EGFR mutations are present in around 15% of NSCLC in Western populations, rising to 35% in Asian populations. EGFR inhibitors are superior to chemotherapy in the first line treatment of these patients. However, despite high response rates and good progression-free survival, patients invariably develop resistance to drugs such as erlotinib and gefitinib. In the majority of patients this resistance is mediated by a T790M mutation.”
“Combination immunotherapy as second or third line treatment extends overall survival to at least 15 months in patients with pleural malignant mesothelioma, according to late-breaking results from the MAPS2 trial presented today at the ESMO 2017 Congress in Madrid.
“Malignant pleural mesothelioma (MPM) is a rare disease usually caused by occupational exposure to asbestos. First line therapy is pemetrexed and platinum chemotherapy, with or without bevacizumab. There is no approved second line treatment and drugs that have been tested in this setting had low efficacy, with a disease control rate under 30%. Phase II studies have shown promising activity of checkpoint inhibitors as second line treatment.”
“The jackpot cancer immunotherapy ambitions of AstraZeneca stumbled in July with the failure of a closely watched clinical trial in newly diagnosed lung cancer. Friday, the Anglo-Swedish drugmaker attempts a recovery with positive results from a new study, also in lung cancer, but aimed at a niche group of patients.
“AstraZeneca still trails cancer immunotherapy leaders Merck and Bristol-Myers Squibb, but staking a claim in lung cancer marks progress.”
“A majority of patients with advanced melanoma responded to the combination of pembrolizumab (Keytruda) and the investigational IDO1 inhibitor epacadostat, as reported at the European Society of Medical Oncology congress in Madrid.
“In phase I/II results from the ECHO-202/KEYNOTE-037 trial, the combination induced objective responses in 29 of 53 (55%) efficacy-evaluable untreated patients, including seven complete responses. Twenty-two of 38 evaluable patients (58%) responded to the recommended phase II dose of epacadostat (100 mg).”
“Swiss drugmaker Novartis notched a trial win for its drug cocktail against skin cancer on Monday, while a rival treatment from Roche with slipping sales failed in a separate study with a similar patient group.
“All the medicines were tested in melanoma patients who had undergone surgery to cut out tumors and had a genetic mutation called BRAF, making them likely to respond to the targeted cancer pills. Patients with BRAF mutations constitute around half of the melanoma population.”
“In a head-to-head comparison of two immunotherapy drugs used to prevent relapse in certain patients with advanced melanoma, one treatment was the clear winner — and it’s not the one that most people get.
“The international study, released Sunday, involved 900 patients whose tumors were removed by surgery but who remained at high risk of recurrence of melanoma, an often aggressive form of skin cancer.”
